Seems like ou have a transmission problem. If the motor is running but you cant go anywhere your transmission is not converting the power that is generated by you motor.

Meaning od dtc p1733 on suzuki aerio. what should be done?


get it serviced, the operators guide told you that.
or is this a DIY question? got tools, got scan tool, ? skills?
meaning, well it means some tests failed, on board diagnostics
ran tests (it never stops) and found errors, P1733 is one.
rule 1, only use suzuki books for this error, no others, (no fords,etc)
the suzuki factory service manuals covers this, called the FSM.
the meaning can very by transmission you have.
i think its a transmission code, (3 > 4 shift)? transmission slip.
get it serviced, or diagnoseds.
or reset it
drive
and see if that comes back, like on all dtc errors.

How to check diagnotic codes through radio


So Mitsubishi threw a curve ball, eh? I've seen a few cars where you can access some but not all trouble codes by the ignition switch (On, off, on, off, and on. Then codes will flash on the check engine light.) But the radio?? Check with the dealer, John. Good luck.

Get proper diagnostic test done first of all, than if you have replaced the temperature sensor, get the error codes reset in the ECU. Anyway once you get proper diagnostics done you will know what is really wrong

After engine get warmed up, rpm's rise, then lower, then engine stalls. Diagnotic shows no codes


when my dodge truck done that, it was the head... when i took the head off, i found a hair line crack in between the intake and exhaust valves.... it ran fine until the engine got warm..... then the truck shut down, would not start back up until it cooled down.. check and see if there is any water in your oil, that would be a sign of head problem... if not then check and see if the catalytic converter is clogged ( do that by looking/ under the vehicle to see if the catalytic converter is red or if it feels hot when you put your had near it.... DO NOT TOUCH IT..... if pipe is cool at the end and it is hot, most always means it is clogged) hope this helps.... NEITHER OF THESE PROBLEMS SHOW UP ON A COMPUTER DIAGNOSTICS....

Hi a had a service & they ran the diagnostic test as my warning light was coming on (ABS).This started when I had my brakes done & ever since then it comes on.They could find what the problem was....


Instead of pulling a fuse that will make ur abs not functional, let the scan be done and log on to http://www.troublecodes.net/audi/

for more understanding of the error codes.

Good luck.

I have a 92 chevy 3500 w/ throttle body 2wd. its showing me error code 12. the manual doesnt have a 12 code for this truck.


code 12 is the diagnostic code. its only purpose is to let you know that the system is in diagnostic mode. if this is the only code you are getting, your system is fine.
